Buyer unsuccessful in contacting the supplier to pay off his debt

Q: I am inquiring in regards to business items I purchased from a supplier on a loan at a Business Expo. We had a mutual agreement to pay for the items on a later date. The supplier had provided me with his contact details to pay him back.

I had lost the suppliers number and cannot locate the person which I got the business items from. Also, I tried going to the Business Expo next year but the person did not come back the next year. I have tried going there for the past 4 years at the expo and the person has not come there. I am not sure if he has any relatives or friends either.

Please advise what I can do in regards to the money I owe him.

Breastfeeding while pregnant

Q: I have a one and a half year old daughter and my intention was to breastfeed her till she reaches the age of 2 as per the Islamic ruling.

However I have just found out that I am pregnant again, Alhamdulillah.

My question is: is it permissible for me to continue breastfeeding while pregnant, or is it advisable to stop asap?

Three talaaqs

Q: My husband first gave one talaq but we resume (ruju) our relation. After few weeks he gave 2 talaq in extreme anger which I didn't listen because he didn't say them clearly. When I said say out loud and clear he remained quite. Later he said I did't have the intention to give you talaq.

I have two kids of 4 and 5 years age. So what does Islam say in this situation if 3 talaqs are complete or we have to do another nikah because of kinaya talaq?
